Description
Fremgangsmåte for fremstilling av en kontinuerlig Method for producing a continuous
bane av polymert skum, og innretning for utførelse web of polymeric foam, and device for execution
av fremgangsmåten. of the procedure.
Oppfinnelsen vedrører fremstilling av en kontinuerlig^The invention relates to the production of a continuous^
bane av polymert skum fra en blanding av flytende skumreaktanter, hvor man kontinuerlig tilfører en blanding av flytende skumreaktanter til bunnen av en beholder og tillater blandingen å ekspandere oppover i beholderen som følge av en kjemisk reaksjon mellom reaktantene. web of polymeric foam from a mixture of liquid foam reactants, where one continuously adds a mixture of liquid foam reactants to the bottom of a container and allows the mixture to expand upwards in the container as a result of a chemical reaction between the reactants.
Vanligvis fremstilles skumplastbaner med en viss bredde Usually, foam plastic webs are produced with a certain width
ved at et hensiktsmessig på forhånd dannet skummemedium påføres en foliebane, f.eks. av papir, som beveges i produksjonsretningen ved hjelp av en transportør, eller som utgjør en del av en transportør, idet skummemedium fordeles jevnt over banen hvorpå mediet begynner å ese. Por å unngå at esingen forplanter seg bakover heller banen in that a suitably preformed foam medium is applied to a foil web, e.g. of paper, which is moved in the production direction by means of a conveyor, or which forms part of a conveyor, the foaming medium being distributed evenly over the path on which the medium begins to rise. Try to avoid the esing propagating backwards rather than the path
vanligvis svakt nedover. Friskt blandet skummedium har lett for å flyte i produksjonsretningen og hellingen på transportbanen eller underlagsbanen må derfor begrenses tilsvarende. Por å hindre at det påførte medium og senere skummet flyter til sidene benyttes begrensningsvegger. usually slightly downward. Freshly mixed foam medium tends to flow in the direction of production and the slope of the transport track or substrate track must therefore be limited accordingly. To prevent the applied medium and later the foam from flowing to the sides, limiting walls are used.
Ved denne fremstilling av skumplast har man den ulempe With this production of foam plastic, one has the disadvantage
at bunnpartiet og toppartiet til den fremstilte skumplastbane får en annen konsistens enn materialet i det mellomliggende parti, og det vil vanligvis være tyngre enn dette. Når mediet eser opp til skum på underlaget, dannes avrundede skulderpartier langs sidene, slik at man ikke får en bane med rent rektangulært tverrsnitt. De nevnte forhold bevirker at skumplastbanen etter herding vanligvis må renskjæres slik at hare materialet med homogen beskaffenhet blir igjen, og denne renskårne, bane skjæres så opp i tynnere baner eller blokker. that the bottom part and the top part of the manufactured foam plastic web have a different consistency than the material in the intermediate part, and it will usually be heavier than this. When the medium foams up on the substrate, rounded shoulder areas are formed along the sides, so that you do not get a path with a purely rectangular cross-section. The aforementioned conditions mean that, after curing, the foam plastic sheet usually has to be cleanly cut so that the coarse material with a homogeneous nature remains, and this cleanly cut sheet is then cut into thinner sheets or blocks.
Produksjonen kan derfor gjøres adskillig mer økonomisk hvis mengden av det materiale som skal skjæres bort reduseres eller hvis renskjæringen kan sløyfes helt. Det vil også være klart at jo tykkere eller høyere banen er, desto mindre vil avfallsandelen pr. produksjonsenhet bli. Production can therefore be made much more economical if the amount of material to be cut away is reduced or if clean cutting can be omitted entirely. It will also be clear that the thicker or higher the track, the smaller the proportion of waste per production unit become.
Fra DAS nr. 1.169.648 er det kjent en innretning for fremstilling av skumplastblokker eller -baner. Den skumstoff-dannende kemikalieblanding innføres i en loddrett stående, sjakt-lignende form hvor flater som begrenser skumstoffstrengens sider beveger seg kontinuerlig oppover. Det dreier seg altså ved denne kjente teknikk om en blokkstøping som foregår vertikalt oppad. From DAS No. 1,169,648, a device for the production of foam plastic blocks or webs is known. The foam-forming chemical mixture is introduced in a vertically standing, shaft-like form where surfaces that limit the sides of the foam strand move continuously upwards. This known technique therefore involves a block casting that takes place vertically upwards.
Til forskjell herfra tar man med oppfinnelsen sikte på In contrast to this, the invention aims at
å "la den innledende skumming skje oppover i en beholder, mens ferdigekspanderingen skal skje i en i og for seg kjent renneformet transportør. to "allow the initial foaming to take place upwards in a container, while the final expansion shall take place in a per se known chute-shaped conveyor.
Derved oppnår man det som er hovedhensikten med oppfinnelsen, nemlig å muliggjøre billigere fremstilling av s:kumplast-baner, ved økning av banens tykkelse henholdsvis høyde ved fremstilling av et produkt som har så å si rent rektangulært tverrsnitt. Dette har man ifølge oppfinrielsen oppnådd ved hjelp av en fremgangsmåte som angitt i krav 1. Som nevnt omfatter oppfinnelsen også en innretning for utførelse av den nye fremgangsmåte, og innretningen utmerker seg ved de trekk som er angitt i krav 2. Ytterligere Thereby one achieves what is the main purpose of the invention, namely to enable cheaper production of s:kumplast webs, by increasing the web's thickness or height when manufacturing a product that has, so to speak, a purely rectangular cross-section. According to the invention, this has been achieved by means of a method as stated in claim 1. As mentioned, the invention also includes a device for carrying out the new method, and the device is distinguished by the features stated in claim 2. Furthermore
trekk ved innretningen er angitt i krav 3. features of the device are stated in claim 3.
Fordelen ved at esingen av skummemediet er kommet vel The advantage is that the foaming medium has arrived well
i gang før mediet overføres til transportbanen er iøynefallende. Massen som kommer ut på banen, er mer sakteflytende og kan ledes henover en meget brattere bane enn hva som var mulig hittil. Ved konvensjonelle anlegg ligger hellingen mellom 2 og 8°, mens man ved utførelsen ifølge oppfinnelsen uten videre kan tillate en helling på 15°. Hellingen og lengden på skråbanen avpasses slik at esingen er i det vesentlige avsluttet når materialet har passert skråbanen. Deretter overføres skummaterialet til en horisontal bane hvor materialet er helt eller praktisk helt uteset og hvor herdingen finner sted. Den nye fremgangsmåte tillater eksempelvis uten videre støping av plastbane med f. eks. 2 menters tykkelse. Svinnprosenten er redusert meget betydelig og man kan regne med besparelse på 6 til 10$ i forhold til den tidligere kjente og anvendte teknikk. in progress before the medium is transferred to the conveyor belt is conspicuous. The mass that comes out onto the track is more slow-flowing and can be guided over a much steeper track than was possible until now. With conventional installations, the slope is between 2 and 8°, while with the design according to the invention, a slope of 15° can be allowed without further ado. The slope and length of the inclined path are adjusted so that the etching is essentially finished when the material has passed the inclined path. The foam material is then transferred to a horizontal path where the material is completely or practically completely exposed and where curing takes place. The new method allows, for example, the casting of plastic webs with e.g. 2 ment thickness. The percentage of waste has been reduced very significantly and you can count on a saving of 6 to 10$ compared to the previously known and used technique.
Ved fremstilling av skumplastbane med mindre tykkelse In the production of foam plastic web with less thickness
kan skråbanen sløyfes helt slik at det delvis utesede materiale med en gang overføres til en horisontal transportbane. the inclined track can be completely looped so that the partially screened material is immediately transferred to a horizontal transport track.
Oppfinnelsen skal forklares nærmere ved hjelp av et utførelseseksempel som er vist rent skjematisk på tegningen i form av et snitt gjennom en innretning for utførelse av den nye fremgangsmåte. The invention shall be explained in more detail by means of an embodiment which is shown purely schematically in the drawing in the form of a section through a device for carrying out the new method.
En tilførselsinnretning eller blandeinnretning for kemikalier som omdannes til skumplast er betegnet med A. Tilførsels-innretningen er ved hjelp av en tilførselsledning B forbundet med en beholder D hvis bredde stort sett svarer til den fremstilte plastbanes bredde. Beholderens nedre del står i forbindelse med tilførselsledningen B og beholderens bakvegg er i utførelseseksemplet høyere enn beholderens fremre vegg. Beholderens nedre parti tiltar gradvis i tverrsnitt og går over i et øvre parti med stort sett konstant tverrsnitt. Foran og innved beholderens fremre kant løper en transportbane E av papir som avvikles fra en nedenfor behoLderen beliggende forrådsrull F. Som vist utgjør et parti av den til -å begynne med vertikalt oppover forløpende papirbane E en del av beholderens D fremre vegg henholdsvis en forlengelse oppover av denne vegg fra beholderens fremre kant M før banen over en lederull L avbøyes på skrå nedover og fremover. A supply device or mixing device for chemicals that are converted into foam plastic is denoted by A. The supply device is connected by means of a supply line B to a container D whose width largely corresponds to the width of the produced plastic web. The lower part of the container is connected to the supply line B and the rear wall of the container is higher in the design example than the front wall of the container. The lower part of the container gradually increases in cross-section and transitions into an upper part with a largely constant cross-section. In front of and inside the front edge of the container runs a transport path E of paper which is unwound from a supply roll F located below the container. As shown, a part of the initially vertically upwards running paper path E forms part of the front wall of the container D or an extension upwards of this wall from the container's front edge M before the path over a conductor roll L is deflected obliquely downwards and forwards.
Til høyre på tegningen er det vist et endeløst transport-bånd I. Transportbåndet løper over en lederull slik at transport-båndets øvre løp beveger seg i den med pilen viste retning stort sett i horisontalplanet. Mellom transportbåndet I og den ved beholderen liggende lederull L strekker det seg en skrå støttebunn G med betydelig helling. Papirhanen E løper nedover langs støtte- To the right of the drawing, an endless conveyor belt I is shown. The conveyor belt runs over a guide roller so that the upper run of the conveyor belt moves in the direction shown by the arrow, largely in the horizontal plane. Between the conveyor belt I and the conductor roll L lying next to the container, there is an inclined support base G with a considerable slope. The paper tap E runs downwards along the support
bunnen G og deretter videre i det vesentlige horisontalt på transportbåndet I. Det er anordnet sidevegger som'"begrenser banens ut- the bottom G and then further essentially horizontally on the conveyor belt I. There are side walls which limit the path's out-
strekning i sideretningen, som vanlig ved maskiner av denne art. stretch in the lateral direction, as usual with machines of this kind.
Disse sidevegger, støttebunnen G og transportbåndet I danner en renneformet transportør K. Denne renneformede, transportør K er tilordnet det av rullen L dannede overløp J. These side walls, the support base G and the conveyor belt I form a chute-shaped conveyor K. This chute-shaped conveyor K is assigned to the overflow J formed by the roller L.
Skumplastbanen fremstilles på følgende måte: The foam plastic web is produced in the following way:
Blandingsmediet tilføres beholderens D nedre parti i en The mixing medium is supplied to the lower part of the container D in a
slik mengde at mediet får anledning til å ekspandere eller ese i beholderen, hvor ekspansjonsretningen er høyderetningen. Da beholderens bakre vegg er høyere enn den fremre vegg, som i dette tilfelle tildels består av papirbanen E, vil massen når den har nådd overløpet J, velte over på den av støttebunnen G dannede skrå-flate, mens esingen fortsetter slik at banen vokser i høyden. such an amount that the medium has the opportunity to expand or swell in the container, where the direction of expansion is the direction of height. As the rear wall of the container is higher than the front wall, which in this case partly consists of the paper web E, the mass, when it has reached the overflow J, will tip over onto the inclined surface formed by the support base G, while the esing continues so that the web grows in the height.
Forholdene tilpasses slik at høyden over skråbanens inngangsparti, dvs. der hvor lederullen L, og altså overløpet J befinner seg, holdes i det vesentlige konstant og slik at det skummende mediums øvre grenseflate holdes i det vesentlige i ett plan. Når massen har nådd den horisontale transportbane, er den i det vesentlige uteset. The conditions are adapted so that the height above the entrance part of the incline, i.e. where the guide roll L, and therefore the overflow J is located, is kept essentially constant and so that the upper boundary surface of the foaming medium is kept essentially in one plane. When the mass has reached the horizontal transport path, it is essentially outside.
Da beholdren D har omtrent samme bredde som papirbanen As the container D has approximately the same width as the paper web
E, kan de kjente frem og tilbake svingende fordelingsinnretninger E, the known back and forth oscillating distribution devices can
for tilførsel av utgangsmaterialer sløyfes. for the supply of starting materials is bypassed.
Beholderens D fremre vegg kan eventuelt trekkes helt opp The front wall of the container D can optionally be pulled up completely
mot skråbanens topp, dvs. opp mot overløpet. Beholderen kan også være oppdelt i seksjoner ved hjelp av parallelle skillevegger som ligger i plan parallelle med tegningsplanet, og hver seksjon kan da ha sitt eget innløp. towards the top of the ramp, i.e. up towards the spillway. The container can also be divided into sections by means of parallel partitions which lie in a plane parallel to the drawing plane, and each section can then have its own inlet.
